VAPOR-TUBE CLEANER.

SPECIFICATION forming part of Letters Patent No. 632,493, datedSeptember 5, 1899.

Application filed December 2, 1898. Serial No. 698,112. No model.)

To all whom. it may concern:

Be it known that I, ARTHUR KITSON, a subject of the Queen of GreatBritain, and a resident of Philadelphia, county of Philadelphia, Stateof Pennsylvania, have invented certain new and useful Improvements inVapor-Tube Cleaners, of which the following is a specification.

My invention relates to vapor-burning apparatus, and more particularlyconsists in an improved form of vapor-tube cleaner for keeping thedischarge-opening of the vaporizingtubes used in such apparatus freefrom carbon and other impurities which tend to collect therein andinterfere with the discharge of vapor.

The preferred form of apparatus embodying my invention is shown in theaccompanying sheet of drawings, in which- Figure 1 is a side elevationof a vaporburning apparatus with the muffler shown in section. Fig. 2 isa central section, enlarged, from Fig. 1. Fig. is a similar centralsection taken on a plane at right angles to the plane of Fig. 2. Fig. 4.is a detail side elevation similar to Fig. 2, showing thereversing-lever in various positions. Fig. 5 is a plan View of Fig. 3,and Fig. 6 is a section on line 6 6 of Fig. 2 with the vaporizing-tuberemoved.

Throughout the drawings like referencefigures refer to like parts.

The vapor-burning apparatus is generally represented by the numeral 1.This vaporburning apparatus may of course be of any desirable form; butI have illustrated that shown and described in my pending application,Serial No. 674,573, filed March 21, 1898.

2 is the vaporizing-tube of such vapor-burning apparatus, which has thedischarge-opening 3 preferably made in the form of apunched up portionof the side wall of said tube, as shown. 4 is a cleaning-needle mountedopposite to said discharge-opening 3 and provided with means forprojecting it into said opening and withdrawing it therefrom.

The preferred form of means for moving the needle, as shown, consists ofthe parallelmotion mechanism or frame 5, on which the needle is mounted.This frame 5 is carried by the two sets of swinging arms 6 and 7, whichare pivoted to the bed-piece 8. This bed-piece, and consequently theWhole parallel-m otion mechanism or other form of hinged frame, isremovably mounted on the vaporizing apparatus by means of thespring-hookshaped projection 9, which slips over the mouth of themixing-tube 10. The swinging piece 7 may be made solid, as shown, ormight be made U-shaped, the lower swinging piece 6, however, being shownin such position that it falls below the vaporizing-tube 2 and must bemade U-shaped, as shown in Fig. 6. This piece 6 is pivoted on thefoundation-piece S by the pin 15, and the piece 7 is similarly pivotedby the pin or shaft 11, which latter is rigidly connected with the piece7 by means of the short cross-pin 16 (see Figs. 2, 3, and 5) or someother similar device. The parallel-moving piece 5 is also made double toencompass the vaporizing-tube and is composed of the two parallelportions 5 and 5, as shown in Figs. 3 and 6, connected at the bottom, asshown in Fig. 3.

Various means for giving vibrating motion to the swinging frame could beused; butI have shown the pivoted shaft 1]. of the piece 7 extended anda reversing-lever 12 mounted thereon. From either end of thisreversinglever pendantsin the form of chains or cords 13 1a may besuspended to aflord convenient means for moving the lever.

The method of operating my invention is evident from the foregoing. Bypulling the pendant 14 until the reversing-lever 12 reaches the limit ofits motion (shown in dotted lines in Fig. 4) the frame 5 and needle 4will be thrust down out of the way of the issuing jet of vapor, theneedle keeping the position indicated in dotted lines in Fig. 2. Bypulling on the pendant 13 until the lever reaches its extreme limit ofmotion in the other directionto wit, the dotted-line horizontal positionshownin Fig. 4.the needle 4 will be in- 5 line position of Fig. 4 to thefull-line position therein shown, the cleaning of the dischargeopeningcan be thoroughly done. The pendant 14 is then given a final pull,throwing the needle down into the lowermost position, and the lamp canproceed in its operation without being interfered with by the needle.

It is evident,of course, that various changes could be made in thedetails of the apparatus above described without departing from thespirit and scope of my invention so long as the relative arrangement ofthe parts shown in the drawings and principle of operation set out inthe specification are preserved. Other means than the positive pull bythe operator might be employed to move the needle in and out, othermeans of guiding the needle to and from the opening might be employed,and various modifications be made to adapt the cleaner to differentstyles of lamp; but all these I consider within the limit of myinvention.

Having therefore described my invention, what I claim as new, and desireto protect by Letters Patent, is

1. In a vapor-burning apparatus the combination with a vaporizing-tubehaving a discharge-opening, of a hinged frame, a cleaningneedle on saidframe so disposed as to come opposite the discharge-opening or to bewithdrawn to one side of the line of discharge, and means for vibratingthe hinged frame, substantially as described.

2. In a vapor-burning apparatus the combination with a vaporizing-tubehaving a discharge-openingin its side, of a hinged frame, acleaning-needle on said frame, so disposed as to come opposite thedischarge-opening or to be withdrawn to one side of the line ofdischarge, and means for vibrating the hinged frame, substantially asdescribed.

3. In a vapor-burning apparatus the combination with a vaporizing-tubehaving a discharge-opening in its side, of a hinged frame,

removably mounted on the vapor-burning apparatus, a cleaning-needle onsaid frame so disposed as to come opposite the dischargeopening or to bewithdrawn to one side of the line of discharge, and means for vibratingthe hinged frame, substantially as described.

4. In a vapor-burning apparatus the combination with a vaporizing-tubehaving a discharge-opening in its side, of a hinged frame, consisting ofa parallel-motion mechanism, a cleaning-needle on said frame so disposedas to come opposite the discharge-opening or to be withdrawn to one sideof the line of discharge, and means for vibrating the hinged frame,substantially as described.

5. In a vapor-burning apparatus the combination with a vaporizing-tubehaving a discharge-opening in its side, of a hinged frame consisting ofa parallel-motion mechanism, a cleaning-needle on said frame, sodisposed as to come opposite the discharge opening or to be withdrawn toone side of the line of discharge, and a reversing-lever mounted on oneof the pivot-shafts of said parallel-motion mechanism substantially asdescribed.

6. In a vapor-burning apparatus the com bination with a vaporizing-tubehavinga discharge-opening in its side, of a hinged frame consisting of aparallel-motion mechanism, a cleaning-needle on said frame, so disposedas to come opposite the discharge-opening or to be withdrawn to one sideof the line of discharge, and a reversing-lever mounted on one of thepivot-shafts of said parallel-motion mechanism, together with pendantsfrom the two arms of said lever, substantially as described.
